Good quality, fast drying

Works well for detecting oil contamination. The ink dries quickly which is great for production speed, though you need to be precise with application.

Reliable German engineering

We switched to these from a cheaper alternative and the difference in consistency is night and day. Highly recommended for quality control labs.

Good but pricey

The performance is excellent and very accurate, but the price point is higher than other brands. You get what you pay for in terms of reliability though.

Perfect for adhesion testing

Using these to ensure proper adhesion for coating processes. The dyne levels are clearly marked and the pen feels sturdy in hand.

5 FAQ

Q: How long does the ink last once the pen is opened?

A: Once opened, the ink typically remains effective for about 6 months if the cap is sealed tightly after each use and stored correctly.

Q: What range of dyne levels does this specific pen cover?

A: This specific model is calibrated for a single dyne level as indicated on the label. We offer sets covering 30 to 72 dynes/cm if you need a full range.

Q: Is there a certificate of analysis included with the pen?

A: Yes, each batch comes with a digital certificate of analysis available via QR code on the packaging or downloadable from our website.

Q: What should I do if the ink spreads immediately?

A: If the ink spreads immediately, it indicates the surface tension of the material is higher than the dyne level of the pen. You should test with a higher dyne level pen.

Q: Can these pens be used on metal surfaces?

A: Yes, they are suitable for testing surface tension on various substrates including treated metals, plastics, and foils.
